NASA's next 'top model,' the fruit fly

NASA finds the common fruit fly—Drosophila melanogaster—quite an attractive "model," but not in the way you might think. This tiny insect is a biomedical research model that can reveal the basis for health and disease ...

Immunoproteasome crystal structure determined

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells ...

Cancer-causing virus strikes genetically vulnerable horses

Sarcoid skin tumors are the most common form of cancer in horses, but little is known about why the papillomavirus behind them strikes some horses and not others. A new study by an international research group led by scientists ...

New information on the waste-disposal units of living cells

Important new information on one of the most critical protein machines in living cells has been reported by a team of researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and ...

Scientists see human immune response in the fruit fly

Washington State University researchers have seen how both humans and fruit flies deploy a protein that a plays a critical role in their immune responses to invading bacteria. The discovery gives scientists evolutionary insight ...

10 to 1: Bugs win in NASA study

Bugs are winning out, and that's a good thing according to NASA's Human Research Program. As part of NASA's One-Year Mission, researchers are studying how microbes living on astronauts' skin, inside their bodies and on the ...
